dent of New Rochelle, county of Vest-V chester, State of New York, haveinvented a new and useful Improvement in SashiPulleys and WindowFrames,of which the following isa specification.

This is a division of my application filed.

December 12, 1912 and allowed May 7, 1913, Serial No. 736,276.

Heretofore when three sashes have been hung side by side so as to form atriple wim dow, and the weights have been suspended in wells at eachside of the windows but not between any two of them, it has beennecessary to fix some of these pulleys in the win-. dow frame before thesame is inserted in a building, with the result that when a pulleybecame broken or otherwise injured so as to be unfit for use, it hasbeen impossible to repair or renew the pulley without mutilating theframe or the building.

The object of my invention is to provide a pulley which can be eitherinserted or removed after the frame is in place and after the buildingis otherwise complete, so as to in no way interfere with the frame orotherparts of the building when the pulleys and sashes are inserted.This object is accomplished by my invention, one embodiment of which ishereinafter set forth.

For a more particular description of my invention, reference is to behad to the no companying drawings, forming a part hereof, in which YFigure 1 is a sectional View of a frame provided with my improvedpulley. Fig. 2 is a plan view of the structure shown in Fig. 1. Fig. 3is a side elevation of my improved pulley in its detached condition,Fig. 4 is a plan view of the structure shown in Fig. 3. Fig. 5 is adiagrammatic view of a triple window embodying my invention.

- Throughout the various views of the drawings, similar referencecharacters designate similar parts. p

In Fig. 1 is shown the left-hand side of the upper portion of a frame,in section, of a triple window, the other corner being symmetricaltherewith, so that a description of one will answer for both. The frame1 is placed below a lintel (not shown) and is provided with four wells,2, 3, 4E and 5 in which suitable sash weights 6 are hung by chains 7 andS or other suitable means. These chains 7 and 8 pass over suitablepulleys 9 and 10, both of which are mounted in the top of the-frame 1,the pulley 10 being a double pulley, that is, a pulley with two sheavesmounted on a single spindle, so that one end of the chain 8 can go overone sheave and the other end over the other, with the result thatoneweight can balance a sash. The chain 7 balances only half a sash, and soruns over a single sheave 11 mounted on a spindle 12 in the casting orhood 13 of the pulley 9. The casting 13 is provided with a suitable base1-1 with an interior slot 15, into which extend suitable guiding lugs 16between which is formed a. suitable groove that receives a flange 1'? atthe lower edge of the casting 13. This casting 13 is preferably made inthe shape of a hood so as to cover the sheave and protect the rear faceof the same. The front and lower faces are open so as to allow for theinsertion or removal of the chain 7. A portion of the casting 13 is cutaway at 18 to form a recess which will enable this hood or casting toget close to the pulley 10 without interfer- 7 ing with thesame.

By reference to Fig. 5 the advantages of my invention will be apparent.Here the lower sashes of the window are designated 20 and 21, the sash21 being placed in the middle window between the sashes 20 and 20. Toavoid confusion only the lower sashes are shown in each instance. Fromthis view it is clear that the center sash 21 is provided with thechains 7 which run over the pulleys 22 to the pulleys 11, as abovedescribed, whereby the sash 21 is always counterbalanced. It is notpossible to put sash weights in the parts 24 of the frame which separatethe sashes 21 and 22, because the parts are not wide enough to permitthis. The sashes 20 are supported by the chains 8 which run over thepulleys 23 and 10, as shown. It will be noted that when the sashes arebalanced, as above indicated, the counter-weights 6 are at each side ofthe triple window.

From the foregoing the use and operation of my improved pulley will bereadily understood. When the sash frame is built, suitable mortises aremade for the pulleys 9 and 10 and the other pulleys (not shown), andsuitable openings are made for the chains. The base 14 for each pulley 9is 7 Copies of this patent may be obtained for made for the purpose. When the sash frame is in the building and ready for use,

a casting or hood 13 for each base ll with its sheave 11 mounted on aspindle 12 is passed through the opening left for the pul- -,';1ey l andshifted'until the flange 17 engages the lugs 16 and is shoved home sothat the base 1 5 securely holds this casting or hood-'13. The chain 7and the parts connected therewith are then put in position thechainpassi-ng through the sheave 11 and then the pulley is put in placeafter which the chain 8 and theparts connected therewith aresuitablymounted. The placing of 'thepulley 10 secures the casting 13 so that thesame cannot be moved enough so as to interfere in'any Way with theoperation of the pulley 9.

While I have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto, but is broad enough to coverall structures that come Within the scope of the annexed claim.

What I claim is:

A indow frame having a pair of Wells for sash Weights in substantialalinement With the plane of the Window frame, a base mounted on theframe to overhang the outer Well, a hood having a pulley journaledtherein removably mounted on said base and a second hood and pulleyhaving a base mounted on the frame to overhang the inner Well, thesecond hood being arranged to prevent the removal of the first hood andpulley;
